Bug #2669: Too much load on reload/restart due to helper initialization

Date: 2014-12-12State: openClass: nastinessComponent: core

During reload or start of the core all helper processes are initialized.This leads to a lot of load, scaling with the number of helpers. This shouldbe optimized, for example by removing the initialization during reload or notinitializing all workers at once (initialize in groups of X processes at once)
